Also how would you integrate 6/x^2 ?

Thanks

What have you got so far?

Hint: write the expressions in the form

So for differentiating 8/√x i've got 8/x^3/2

Not quite. Do you know how to differentiate something like ? Consider what rule you're using, and apply that to this question.

Yep because for 8/√x I've got 8/X^3/2 is that right ?

From here you can use the standard differentiation power rule. The rearranging is the same idea in the second question, then you can do the standard add 1 to the power and then divide by the new power rule.

No, not sure how you got there, try using

Oh yes i know where i went wrong thanks
How would you do 4√x
12. sqrx=x^1/2 so 4sqrx=4x^1/2
13. Then you differentiate accordingly
14. Thanks guys i've worked it out

Just rewrite them both using powers.
square root x = x^1/2
etc..

Also, just remember: 8/√x is = 8 * 1/√x
and dont forget the +C when integrating XD until you come to C2.
